These models can include requirements, architecture, behavior, interfaces, and performance parameters. By having a holistic view of the system, decision-makers can make more informed choices about resource allocation. They can identify areas of redundancy, eliminate unnecessary components, and optimize the allocation of personnel, equipment, and budgetary resources.
Decision-makers can analyze the impact of different resource configurations on system performance, cost, and schedule. They can perform “what-if” analyses to assess trade-offs and identify the most efficient allocation strategies. By conducting these simulations in a virtual environment, the DoD can minimize risks and costs associated with physical prototyping and testing.
The use of standardized modeling languages and frameworks enables a common understanding of system requirements and constraints. This promotes effective communication and coordination among different organizations and disciplines within the DoD. Improved collaboration reduces the likelihood of resource conflicts and ensures that resources are allocated in a coordinated and synergistic manner.
Additionally, MBSE supports iterative and incremental development processes, allowing the DoD to adapt resource allocation strategies over time. As the system evolves and new information becomes available, decision-makers can update the system models and reassess resource allocations accordingly. This flexibility enables the DoD to respond to changing mission requirements, technological advancements, and budget constraints effectively.
